The Bernoullis Principle was a phonomena for all physics He was considered to me the father of mathematical physics The principle itslef was named after the Swiss scientist named Daniel Bernoulli during the eighteenth century Bernoulli studied the many relationships among fluid and pressure This principle shows the relationship of velocity pressure and the height for a steady fluid flow When a horizontal flow is created the speed of the fluid is increased while the pressure it creates decreases The strong example of this is shown through the lift of an airplane in its motion When the speed of the plane begins to increase air is flowed faster over the curved top of the wing rather than the bottom part of the wing underneath When the pressure becomes exerted upwards a net upward force is greated This is called lift This is because the pressure that is exerted downward above the wing is not as great of pressure as being exerted upwards Another example demonstrating this similar method is witnessed in the spoilers of race cars The spoilers are shaped in the image of an upside down wing The curved surface it has in the bottom of the wing is what causes and produces the net downward force In other words a wing with more curvature on the top surface will have a greater lift than a wing with a flat surface The similar application for demonstarting this and helping Bernoulli achieve his conclusion is the Venturi Tube When Bernoulli was studing the flows of fluid as it reached the area in which the the Venturi Tubes pipe diameter was reduced From this Bernoulli stated that the velocity of the fluid flowing through the most narrow diameter is increased while the pressure in that area becomes decreased The Bernoullis Princliple clearly states that the pressure of a fluid that could be liquid or gas decreases when the speed of the fluid
